That’s how yesterday’s Montreal protest is being described today. Hundreds of thousands red-shirted demonstrators defied Quebec’s new “anti-protest” law and marched through the streets of downtown Montreal filling the city with “rivers of red.”

Tuesday marked the 100th day of the growing student protests against austerity measures and tuition increases. In response to the spreading protests, the conservative Charest government passed a new “emergency” law last Friday – Bill 78.

Since Bill 78 passed, people in Montreal neighborhoods have appeared on their balconies and in front of their houses to defiantly bang pots and pans in a clanging protest every night at 8 p.m.Bill 78 mandates:

Fines of between $1,000 and $5,000 for any individual who prevents someone from entering an educational institution or who participate in an illegal demonstration.

Penalties climb to between $7,000 and $35,000 for protest leaders and to between $25,000 and $125,000 for unions or student federations.

All fines DOUBLE for repeat offenders

Public demonstrations involving more than 50 people have to be flagged to authorities eight hours in advance, include itinerary, duration and time at which they are being held. The police may alter any of these elements and non-compliance would render the protest illegal.

Offering encouragement for someone to protest at a school, either tacitly or otherwise, is subject to punishment. The Minister of Education has said that this would include things like ‘tweeting’, ‘facebooking’, and has she has implied that wearing the student protest insignia (a red flag-pin) could also be subject to punishment.

No demonstration can be held within 50 meters of any school campus

Bill 78 not only “enraged civil libertarians and legal experts but also seems to have galvanized ordinary Quebecers.” Since the law passed Friday, people in Montreal neighborhoods have appeared on their balconies and in front of their houses to defiantly bang pots and pans in a clanging protest every night at 8 p.m.

CLASSE spearheaded Tuesday’s march, aided by Quebec’s largest labor federations. The province’s two other main student groups, FEUQ and FECQ, also rallied their supporters.

CLASSE said Monday it would direct members to defy Bill 78, Quebec’s emergency legislation.

The special law was adopted last Friday, suspending the winter semester and imposing strict limits on student protests. Organizers have to submit their itinerary to authorities in advance, or face heavy fines.

CLASSE spokesman Gabriel Nadeau-Dubois said the special legislation goes beyond students and their tuition-hike conflict.

“We want to make the point that there are tens of thousands of citizens who are against this law who think that protesting without asking for a permit is a fundamental right,” he said, walking side by side with other protesters behind a large purple banner.

“If the government wants to apply its law, it will have a lot of work to do. That is part of the objective of the protest today, to underline the fact that this law is absurd and inapplicable.”

A protest organizers described as the single biggest act of civil disobedience in Canadian history choked the streets of downtown Montreal in the middle of Tuesday’s afternoon rush hour as tens of thousands of demonstrators expressed outrage over a provincial law aimed at containing the very sort of march they staged.

Ostensibly Tuesday’s march was to commemorate the 100th day of a strike by Quebec college and university students over the issue of tuition increases. But a decision last Friday by the Charest government to pass Bill 78 – emergency legislation requiring protest organizers to provide police with an itinerary of their march eight hours in advance – not only enraged civil libertarians and legal experts but also seems to have galvanized ordinary Quebecers into marching through the streets of a city that has seen protests staged here nightly for the past seven weeks.

“I didn’t really have a stand when it came to the tuition hikes,” said Montrealer Gilles Marcotte, a 32-year-old office worker who used a vacation day to attend the event. “But when I saw what the law does, not just to students but to everybody, I felt I had to do something. This is all going too far.”

Tuesday’s march was billed as being two demonstrations taking place at the same time. One, organized by the federations representing Quebec college and university students and attended by contingents from the province’s labor movement, abided by the provisions of the law and provided a route. The other, overseen by CLASSE, an umbrella group of students associations, deliberately did not.

By 3: 30 p.m., a little more than 90 minutes after the marches began to snake their way through downtown, CLASSE, which estimated the crowd at 250,000, described the march as “the single biggest act of civil disobedience in Canadian history.”

Other crowd estimates varied between 75,000 and 150,000 protesters. Montreal police do not give official crowd estimates but the Place des festivals, which demonstrators easily filled before the march began, holds roughly 100,000 people.

[…] Shortly before the evening demonstration commenced, supporters in central Montreal districts came out onto their balconies and in front of their homes to bang pots and pans in a seeming call-to-arms.

As well, the powerful Montreal transit union also gave protesters a boost when it called on its members to avoid driving police squads around on city buses during the crowd control operations. Montreal police have for several years used city buses as well as their cruisers to shuttle riot squad officers around to demonstration hotspots and as places to detain prisoners. […]

The daytime march was considered to be one of the biggest protests held in the city and related events were held in New York, Paris, Toronto, Calgary and Vancouver. […]

Gabriel Nadeau-Dubois, co-spokesman for the hardline CLASSE group, described Tuesday’s march as a historic act of civil disobedience and said he was ready to face any legal consequences.
